Animal experiment: | Rats[3]Male Wistar rats (290-450 g) are anesthetized with pentobarbital sodium (35 mg/kg, i.p.) and artificially ventilated with room air. Diastolic blood pressure before the administration of the Midaglizole (Midaglizole) is about 35 mmHg. Midaglizole at doses of 3 and 30 mg/kg produces an increase in blood pressure by 27 and 64 mmHg, respectively, at approximately 1 min after the administration. |

Midaglizole hydrochloride (DG5128) is a preferential α2-adrenoceptor antagonist. Midaglizole hydrochloride (DG5128) exhibits 7.4 times higher affinity (pKi=6.28) toward α2-adrenoceptor than α1-adrenoceptor.
Midaglizole (DG-5128) at concentrations up to 10 μM inhibits [3H]clonidine binding more effectively than it doed [3H]prazosin binding in rat cerebral cortex membranes. The mode of inhibition is homogeneous and consistent with the law of simple mass action[1]. The EC50 values for stimulation of insulin release from rat islets and the MIN6 β-cell line induced by Midaglizole are 200 nM and 24 μM, respectively. The IC50 values for KATP current inhibition induced by Midaglizole are 3.8 μM and 4.4 uM for Kir6.2 and Kir6.2/SUR1 , respectively[2].
Midaglizole (3 and 30 mg/kg, i.v.) increases blood pressure in pithed rats[3].

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
